If she runs a strong campaign she could possibly help Democrats in the 5th district. It’s only Trump+11 and is a suburban seat trending towards Democrats.
Is there any evidence she would be a strong candidate?
She reps a swingy area and has won close elections before, id like to see the stats from her district but I wouldn't be surprised if it was a Trump-Biden District seeing as it's in Knoxville and her margin of victory has expanded the last 3 cycles in a row. Obviously though I don't think she can win look at what happened to breadsen in 2018 but she could do decent enough to help Dems down ballot by raising turnout.
